Google offers a mobile proxy service which makes IP address far less likely to be unique. I was very surprised to find the forum had found several users with the same IP addresses and all were unknowing users of the following service  
[https://developer.chrome.com/multidevice/data-compression](https://developer.chrome.com/multidevice/data-compression)

The result is that the IP address is not correct on the forum. The solution is simple enough, just use the x-forwarded-for header as described in the linked document.
